Admob advertising - most suitable bid..

This is my first time running a campaign and I need some some suggestions on the bid value that I must use…Admob approved my ad today…
My app is for my new game ‘Cheetah run’…I am planning to run the campaign in North America.18-45 age group…

Right now i have set the bid as 0.01$…will that get me enough clicks for full $10 i have allotted for today.or should I increase it…what would you do…the game is

What happens if full 10$ is not spent in a day?will the balance stay in the account or is it lost?

It would be very unusual, if unused balance would be lost. I am almost certain, that it stays available on your account.

sorry but is 0.01$ per 1000 impressions or for single impression?
